I voted for duty because after giving it some consideration that seems to be the most common motive for my characters (and also the most recent). The kind of duty varies wildly, though.
Looking over the list I've had characters with every listed motive except maybe revenge:
I can only remember one character whose motive was most similar to partying:
It was a charismatic orc swordmaster who was basically a coward calling himself adventurer mostly because of he liked to bathe in the admiration of the common folk.
I've often used money as a central motive for either mercenary-style characters or 'traders/looters'. The latter includes a dwarven scholar who accompanied adventurers to write down their stories, travel journals and create maps to sell them to the highest bidder and become famous at the same time.
Power is often a secondary goal, rarely the primary or only goal for my characters.
What I've never done was to create a character without any motivation - I always think of a backstory even if it's just a few sentences short. How else could I roleplay the character?
